EPHRAIM IIAMBUJ ER, OF DETROIT, MICHIGAN, ASSIGN OR OF ONE-FOURTH OF SAME PLACE.

HASP-LOCK.

SPECIFICATION forming part of Letters Patent No. 313,590, dated March 10, 1885.

Application filed October 10, 1884.

To all whom it may concern:

Be it known that I, EPHRAIM HAMBUJER, of Detroit, in the county of Vayne and State of Michigan, having invented new and useful Improvements in Hasp-Locks; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to certain new and useful improvements in hasp-locks, more especially designed for trunks, which will be strong, durable, and economical to manufacture, and which eannotbe unlocked without two manipulations, one of them by means of The invention consists in the peculiar construction of the various parts, their combination, arrangement, and operation, all as more 2o fully hereinafter described.

l Figure l is a front plan view of my improved loek. Fig. 2 is a cross-section of the same on the line x x in Fig. 1. Fig. 3 is a longitudinal section on the line T T in Fig. l,

the parts being detached.

In the accompanying drawings, which form a part of this specification, A represents one part of the hasp, and B the other part, both being secured together by the j oint O. The part A terminates in an enlarged and nearly eircular plate, D, around which extends the outwardly-projecting ilange a, having a een'- tral round aperture, throughl which passes the hollow plug b, which is interiorly threaded,

5 as shown, for a part of its length. The lower end of this plug is provided with an outwardly-projecting flange, c, to prevent its being withdrawn through the central aperture inthe plate D, and there is secured to the outer 4o end of said plug an annular and milled edge flange, d. Vithin the hollow plug b is coneealed the screw e, the head of which is so secured that the screw cannot be withdrawn, while its free rotation is not hindered. An

annular flange, j', is cast upon the rear face of the plate D, which forms a recess within which the hollow plug is concealed and operates.

E is a plate having an exteriorly and interiorly threaded stud, y, formed upon its in- (No model.)

ner face and centrally located, and also having a projecting screw, 7i, projecting centrally from the outer face and east integrally therewith. A chamber of a smaller diameter and a larger diameter is formed by the walls i and j, which are cast with the plate E, as shown in Fig. 2. The part B of thehasp also terminates in an enlarged and nearly circular-plate, F, with which is east a centrally-located and rearwardly-projecting screw, 7c. G and I:I are 6o flange-nuts, the former being designed to engage with the screw l1, and the latter with the screw 7c.

In practice the plate F is secured to the trunk-body at the proper place by inserting the screw k through the front wall, and securing the same by means of the nut H. Then the plate E is secured, in a similar way, by means of the nut G, to the front wall of the trunk-top, so that the langef will, when the 7o part A of the hasp is raised, enter the smaller chamber formed by the walls t', and the plate D will enter the larger chamber formed by the wallsj. The lock is now secured to the trunk, and can be locked by turning the hollow plug b, by means of its milled ilange, until said hollow plug engages with the exterior thread of the stud g'. The screw e, having suitable sockets, meut in its head,isnow turned down to lengage with the interior thread ofthe' Se hollow stud g, and by this means the parts are so secured together that the hollow lockingplug b cannot be released until the screw e is released, which can be done by the use of a proper key made to iit the sockets in the head of such screw. This screw should be provided with, say, a right-hand thread, while the plug b should have a left-hand thread, or these threads should run in an opposite direction, so that in manipulating one it will go not affect the other.

Of course, while this lock is described as attached to a trunk, it will be found equally valuable in all places where a hasp-lock is required.

What I claim as my invention isl. A hasp-lock wherein the locking of the same is obtained by means of two screws, the thread of each running in an opposite direction from that of the other, one of said screws roo being operated by a key and the other by means of a milled flange, substantially as described.

2. In a hasp-lock, the combination of the plates D and E, constructed substantially as described, the former being provided With a rotating and interiorly-threaded hollow plug, b, and the latter with an eXteriorly-threaded rigid stud, g, the parts arranged and operating substantially as and for the purposes specilied.

3. In a hasp-lock, the combination of the plates D and E, constructed substantially as described, the former being provided with a hollow plug, b, interiorly threaded, and having Within it a screw, and the latter having a hollow stud, g, exteriorly and interiorly threaded, arranged and operating as and for the purposes set forth.

4. In a hasp-lock, the plate E, having the 2o exteriorly and interiorly threaded stud g and the screw h, both formed integral with said plate, in combination with the lange-nut G, Y plug b, and screw e, substantially as and for the purpose specified. g

`5. A hasp-lock consisting of the hasp A B and joint C, the plates D and E, the hollow plug b and stud g, the screw e, the screws h 7c, and nuts G H, the parts being constructed, arranged, and operating substantially as and 3o for the purposes set forth. v
